GENERAL CHARACTERISTICS OF STEEL GRADE USED IN THE MANUFACTURE OF CHIMNEYS

Grade AISI 304 – chemical composition, mechanical properties, weldability and corrosion resistance are the most versatile, so it is most often used compared to other grades of steel. This steel also has good low-temperature properties. It is used in the manufacture of components for chimneys, equipment in the mining, chemical, cryogenic, food, dairy and pharmaceutical industries. Today, on the world markets of stainless steel, AISI 304 steel pipe occupies a leading position in the category of the most used in construction. The significant demand for pipes made of AISI 304 steel is due to high physical and chemical characteristics.

Grade AISI 321 – corrosion-resistant, heat-resistant steel. The recommended temperature of use is up to 800 ⁰C, while the service life is quite long. AISI 321 is not susceptible to intergranular corrosion even when welding in mildly corrosive environments, as titanium is included in the alloy. It is used for the manufacture of welded equipment in various industries (pipes, parts of furnace fittings, heat exchangers, nozzles and collectors of exhaust systems, etc.).

AISI 316 grade is an improved version of AISI 304 grade due to molybdenum content and slightly higher nickel content. This alloy significantly increases corrosion resistance in aggressive environments. Molybdenum makes steel more resistant to corrosion in chlorine, seawater and acetic acid fumes. It is used for the manufacture of specialized industrial equipment in the chemical, food, pulp and paper, mining, pharmaceutical, and petrochemical sectors of industry.

Grade AISI 201 - alloyed austenitic alloy AISI 201 is similar in composition to the domestic brand 12Х15Г9ND. This alloy includes 12% chromium, 0.75% silicon, about 9-10% manganese, 1% nickel. Such an alloy allows us to talk about the relatively low price of the AISI 201 pipe, which in most cases plays a decisive role when choosing products of this category.
